I can't really articulate it well, but I guess I can't really imagine who my PC would be in this setting and what their motivation would be. The setting itself is so thematic, atmospheric, and thought evoking, but at the same time a bit abstract and surrealistic that I couldn't figure out my place (as a PC) in its world. Maybe a more specific adventure hook could help here, but if you feel that it would limit the imagination, that's valid, too!
